I failed a trig test today and this is the first test I've ever failed in my life. I usually get mid 80s but not this time.

A road rises 15 m for each 150 m of horizontal
distance. What is the angle of inclination of the
road to the nearest degree?

So I drew a right triangle with base 150m and hypotenuse 15m. How do I find the angle of elevation? The answer is 6 degrees but idk how to get it.

There's no other angle. It's a right triangle so 90 degree angle.

sina divide by a = sinb divided by b

sin 90 divided by 150 = sinb divided by 15

(sin 90 divided by 150) times by 15 = sin b

sin-1 [(sin90 divided by 150) times by 15] = b

the hypotenuse wouldn't be 15, the opposite side from the angle would be 15
